Mexico City, 1970. Héctor Belascoarán leaves his stable office job and beautiful (but unhappy) marriage to pursue the adrenaline-filled life of a private detective. The police are useless, Héctor points out, not to mention corrupt and often in on the crime, so it's up to him to tackle the many unsolved cases that haunt the city he loves.

Because he thinks himself a hero, Héctor narrates each episode in that nostalgic noir way, but the catch is that he is, in fact, no slick savior. Hector is still a rookie, prone to blunders and miscalculations, but his perseverance saves the day. In this way Belascoarán, PI is both a tribute and a sendup of detective films of yore; it references the genre in style and substance, but it isn't above joking about it either. It's proof that you can challenge viewers without sacrificing the laughs, and vice versa.
